Assuming that the daily wages for workers in a particular industry averages Birr 11.90 per day and the standard deviation is Birr 0.40. If the wages are assumed to be normally distributed, determine what percentage of workers receive wages between Birr 12.20 and Birr 13.10 less than Birr 11.00 more than Birr 12.9​

step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

it shoild be o
